PLugin not functioning with Underscores Theme

http://underscores.me/

I just made a new site to be sure there was nothing causing the conflict other than the theme and I was right something is not compatible with the theme for some reason which is odd considering the theme is almost completely bare bones. From what I can tell the calendar is the element causing an issue I also think the list view shortcode is pulling in code without a closing div tag based on what I saw on my actual site I had to throw an extra ending div tag to keep style correct below the shortcode element.

This is kind of urgent in the sense of whether I use this or not for the clients site. I still plan on using this in the future though so keep up the good work I see a lot of promise in the plugin just seems like it has some quarks to work out.
